Title: Tool for fitting floor-installed western style toilet
Inventor: KOBAYASHI JUTARO
IPC: F16B1/02
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To securely fix a western style toilet stool, by integrally forming large diameter collars than true fitting holes of the toilet stool, at the upper part of fixing parts which can be pushed into the fitting holes bored at specified positions on a floor. SOLUTION: A fitting tool A is constituted of a nearly columnar fixing part 6 pushed in the fitting hole 3 for a toilet stool and a collar 8 integrally formed with the fixing part 6. Since the fitting tool A is provided with the collar, it can be always inserted in the floor 2 by a certain constant depth and the whole part of the fixing part 6 can be pushed in the inside of the fitting hole 3 and hence, the fitting tool A can act the maximum friction force on the side face of the fitting hole 3 and the fitting tool A can be securely held by the floor. There is no fear that the fitting tool A is inserted in the fitting hole too deep. And hence, the screwed depth of the fitting screw 5 into the fitting tool A can be always secured so as to be deeper than the necessary minimum depth. In this way, the western style toilet stool can be securely fixed.

Title: Electroconductive member of oxide supreconductive material and system electroconductive member
Inventor: SATO JUNICHI

Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To provide selectability for the mechanical and thermal properties and lessen the electric loss by forming an intended electroconductive member so that it contains at least a sort of oxide superconductor, and using it within a specified range of resistance. SOLUTION: An electrocinductive member using an oxide superconductive material should favorably be used in the resistance range 10<-13> -10<-7> Ω.m as the low resistance-superconductive condition, but it is still more preferably to be used in the range 10<-13> -10<-8> Ω.m to exhibit a smaller resistance than that of non-oxygen copper at room temp. (300K), or in the range 10<-13> -10<-9> Ω.m to exhibit a smaller resistance than that of oxygen-free copper at 77K. The discussion does not destructively apply to such an oxide superconductive material of Cu series containing Bi, but to any which has a high crystal current density and whose amperage able to achieve the low resistance condition is large.
